How to Start a Proxy Reselling Business in 2026

No modems. No SIM plans. No rotation infrastructure. Our open-source proxy-reseller-kit gives you an SDK, a React dashboard, and a full Next.js storefront on top of $4/GB wholesale — so you can ship a branded mobile-proxy business in an afternoon and resell at your own price.

The short answer

To start a proxy reselling business, get a reseller API key from PROXIES.SX, clone the open-source proxy-reseller-kit (MIT), set your brand and prices in one config file, and deploy. You buy bandwidth wholesale at $4/GB (less at volume) and resell at your own price — typically 2–5×. The gateway runs the 4G/5G fleet; you just mint capped customer keys.

Why reselling mobile proxies works in 2026

Demand for clean 4G/5G mobile IPs keeps climbing — scraping teams, social-media operators, ad verification, AI agents. But the barrier to supplying them has always been physical: modems, SIM cards, rotation rigs, uptime. The gateway model removes all of that. PROXIES.SX runs the hardware; you sell access. Your only job is branding, pricing, and support — the parts where a focused operator actually adds value.

The kit makes the software side a non-event too. Instead of building key management, usage metering, billing webhooks, and a customer dashboard from scratch, you clone a maintained, security-reviewed codebase and change a config file.

The economics: buy wholesale, sell retail

Your margin is the spread. Wholesale drops at volume; you keep the difference minus payment fees.

What's inside the proxy-reseller-kit

@proxies-sx/pool-sdk

Typed SDK to mint, cap, top-up, rotate, and delete per-customer keys.

@proxies-sx/pool-portal-react

Drop-in React dashboard so customers self-serve their keys and usage.

Next.js storefront

Full starter app: auth, Stripe billing, Postgres, admin + customer views.

MIT licensed — no attribution required. Security-reviewed: parameterized SQL, mandatory Stripe webhook signature verification, idempotent events, server-side-only API keys, database-backed sessions.

Four ways to integrate — pick your speed

From a full storefront to a single REST call, in any language.

PATH A~10 min

Clone the storefront

Clone apps/starter/, fill .env, set brand + prices in one config file, deploy. A complete branded shop with auth, Stripe, and a customer dashboard.

PATH B~15 min

Embed <PoolPortal />

Drop the React dashboard component into an app you already have. Customers manage their own keys; you keep your existing stack.

PATH C~10 min

SDK only

Use @proxies-sx/pool-sdk in any Node/TS backend to mint, cap, top-up, rotate, and delete keys programmatically.

PATH D~5 min

REST API

Call the reseller endpoints directly from any language with an X-API-Key header. PHP, Go, Python, Ruby — anything that speaks HTTP.

Ship in an afternoon: 5 steps

1

Get a reseller key

Mint your psx_ reseller API key at client.proxies.sx/account.

2

Clone the kit

git clone the repo, cd apps/starter, copy .env.example → .env.

3

Brand it

Set name, colors, logo, support contact, and your price tiers in src/config.ts.

4

Wire billing

Add your Stripe keys (and optionally an x402 wallet for USDC). Run pnpm db:migrate.

5

Ship

pnpm dev locally, then deploy (Docker or Vercel). Your shop mints capped keys on every sale.

mint a capped customer key — @proxies-sx/pool-sdk
import { ProxiesClient } from '@proxies-sx/pool-sdk';

const proxies = new ProxiesClient({
  apiKey: process.env.PROXIES_SX_API_KEY!,      // your psx_ reseller key
  proxyUsername: process.env.PROXIES_SX_USERNAME!,
});

// On every sale, mint a key scoped to what the customer bought:
const key = await proxies.poolKeys.create({
  label: 'customer:alice',
  trafficCapGB: 10,
  expiresAt: new Date(Date.now() + 60 * 86_400_000).toISOString(),
});
// → hand key.secret (pak_...) to the customer. The gateway meters usage.

Two networks, one gateway — plus AI-agent payments

Mobile + residential, your choice

One endpoint, three pools: -mbl- (stable 4G/5G), -peer- (residential), -any- (auto-pick mobile, fallback residential). Country, session stickiness, and rotation are all set in the proxy username.

Accept USDC from AI agents (x402)

The kit ships an x402 flow: an autonomous agent pays in USDC over the HTTP 402 handshake, and your shop mints a pak_ key capped to the payment. A whole new class of customer, no checkout UI required.

Frequently asked questions

How do I start a proxy reselling business?

Get a reseller API key from PROXIES.SX, clone the open-source proxy-reseller-kit, set your brand and prices in one config file, and deploy. The kit ships an SDK, a React customer dashboard, and a full Next.js storefront with Stripe billing — so a branded mobile-proxy shop runs in an afternoon. You buy bandwidth wholesale at $4/GB (less at volume) and resell it at your own price, typically 2–5×.

What is the proxy-reseller-kit?

It is the official open-source (MIT) toolkit from PROXIES.SX for reselling mobile proxies through the Pool Gateway (gw.proxies.sx:7000). It contains @proxies-sx/pool-sdk, the @proxies-sx/pool-portal-react dashboard component, and a Next.js storefront template. You mint per-customer keys with GB caps and expiry, and the gateway handles the actual proxy traffic.

How much can a proxy reseller earn?

Margin is the spread between wholesale and your retail price. Wholesale is $4/GB (dropping to $2.40/GB at volume); resellers commonly price at 2–5× that. On a $4/GB cost, selling at $15/GB is roughly a 3.75× markup before Stripe fees (2.9% + $0.30). Your real margin depends on your pricing, volume tier, and churn — these are directional industry ranges, not guarantees.

Do I need to manage modems or SIM cards?

No. That is the point of the gateway model. PROXIES.SX runs the physical 4G/5G fleet; you connect to a single endpoint (gw.proxies.sx:7000) and mint customer keys via the API. No hardware, no SIM plans, no rotation infrastructure to maintain.

Can my storefront accept AI-agent payments?

Yes. The kit includes an x402 flow: autonomous agents pay in USDC over the HTTP 402 Payment Required handshake, and the kit mints a pak_ key capped to the payment amount. Same margin structure as card payments, no human in the loop.

Where do I get support?

The code lives on GitHub (MIT licensed, issues open). For instant help, join the PROXIES.SX Telegram — t.me/sxproxies for support and t.me/proxies_sx for the community group. Get a reseller key at client.proxies.sx/account.
